Depending on their application, the most cost-effective and resilient storage is to use S3 - though this is not a simple switch since the interface is different to that used by most SAN and NAS products.If they require the storage for running applications for which we have managed services for (e.g. RDS) they may not need any storage (or compute) and instead use those services.
SAN maps to EBS - they can create EBS volumes and attach to EC2 instances similar to using SAN (but without the management headache of the SAN).
NAS would map to a number of different storage services - depending on the protocols the customer use to connect to NAS. They could use EFS for NFS shares, FSx for Windows for Windows SMB shares, File Gateway for storing data on S3 with an SMB of NFS shares.
